摘　　要：聚表剂凭借其良好的增黏性,抗盐性以及乳化特性成为陆相油田潜在的优势驱替剂.以华鼎Ⅰ、海博BI和DG聚表剂为研究对象,分析了影响聚表剂溶液黏度性质的单因素指标,基于改进的模糊综合评判方法对三种聚表剂的粘度性能进行优选;通过并联岩心模型驱油实验对优选结果进行验证.结果表明华鼎Ⅰ的粘度性能最优,DG聚表剂的粘度性能最差;并联岩心驱油实验中以改善剖面能力为验证指标与模糊评价结果相吻合;以采出程度为验证指标与模糊评价结果不吻合,原因在于不同聚表剂之间的洗油能力存在差异.综合来看,改进的模糊数学评判方法对于聚表剂的优选具有一定的参考意义.The polymeric surfactant has become a potential superior displacement agent for the continental oil field due to its good viscosity-increasing,salt-resistance and emulsification properties.In this paper,Huading I,Haibo BI and DG polymeric surfactant were used as research objects to analyze the single-factor index affecting the viscosity properties of polymeric surfactant solutions.Based on the improved fuzzy comprehensive evaluation method,the viscosity properties of three polymeric surfactants were optimized.The preferred results were verified by the parallel core model flooding experiment.The results show that the viscosity performance of Huading I is the best,and the viscosity performance of DG polymeric surfactant is the worst.In the parallel core flooding experiment,the improvement of profile ability is consistent with the fuzzy evaluation results;the recovery factor is not consistent with the fuzzy evaluation results,because the capacity of washing oil between different polymeric surfactants is different.On the whole,the improved fuzzy mathematics evaluation method has certain reference significance for the preference of polymeric surfactants.
